dad's little secret

so i'm a mommy at home and my hubby is like totally dominant, u know? he takes care of everything outside the house n i look after all his stuff here. we've got this thing where he calls me baby or daddy's girl sometimes n tells me what to do around the place. it's kinda funny cus one day he told me to wear something really short and tight for him, i mean, just cuz he wanted to see that. n we did it, but after that night things kinda shifted. now sometimes when we're alone or before bed hes all about making sure i'm his little girl again n i find myself wanting to be obedient more often. does this sound normal? what should i do if it starts feeling too much?
